Air traffic control mid-term conflict detection method and device

Abstract

The invention provides an air traffic control mid-term conflict detection method and device. The method comprises the following steps: determining a protection region of each airplane according to error type of a monitoring airplane group; determining a flight path distribution curve of each airplane; inputting the determined flight path distribution curves to a preset airplane encounter probability model, and carrying out calculation to obtain collision probability of a second monitoring airplane when entering the protection region of a first monitoring airplane; and determining collision danger level of the monitoring airplane group according to the collision probability and preset threshold probability combination. According to the method and device, by introducing various uncertain factor trajectory distribution curves and calculating the collision probability by utilizing the airplane encounter probability model, and meanwhile, by carrying out comparison on the threshold probability combination and the collision probability to judge the collision danger level, air traffic control mid-term conflict probability prediction accuracy is improved, and reference is provided for an air-traffic controller for airspace conflict resolution.

Description

Technical field [0001] The invention relates to the technical field of air traffic control safety control, in particular to a method and device for detecting mid-term conflicts in air traffic control. Background technique [0002] At present, with the rapid development of air transportation, the number of aircraft and the number of flights has increased rapidly, and airports and airspace have become extremely crowded. To ensure the sustainable development of air transportation, efforts must be made to increase the capacity and use efficiency of airports and airspace. This requires early detection of possible conflicts between aircraft. Conflict detection is to determine whether an aircraft enters the protection domain of another aircraft based on the aircraft performance, current flight status, flight plan, controller instructions, weather and other information, so as to detect possible conflicts early and take measures to avoid conflicts In order to ensure the safety of air tra...

Problems solved by technology

The biggest disadvantage of this detection method is that it can only roughly determine whether there will be a conflict between two aircrafts, and the possibility of conflict between the two aircrafts cannot be obtained. If the possibility of conflict is very small, it will be judged as a conflict, resulting in A large number of false alarms occur; in addition, due to the influence of some uncertain factors, there will be some differences between the flight path of the aircraft during the actual flight and the predetermined flight path in the flight plan, for example, differences in high-altitude wind and flight control technology , from uncertain factors such as instruments, the size of the track error caused by these uncertain factors cannot
